[quote name='Pandersen;54297]Hi.I have just recieved my ZT-180 and update to firmware 0827. The only problem is that I can't find a way to make it sleep. In the manual there should be a "RED BUTTON" on the top of the screen to turn off programmes. I don't have that button. The screen turns off after the settings' date=' but I need a way to standby and not turn the device off.[/QUOTE']This question was asked and answered only 10 threads ago - http://www.slatedroid.com/zt-180/6726-zenithink-standby.htmlThe search tool is your best friend!
